Title: Fm detection circuit
Inventor: SATOU TERUO
IPC: H03D3/06
Filed: 1979-06-11
Abstract: PURPOSE:To reduce the distortion of FM detection and to increase the S/N, by constituting the phase shifter with dual tuning circuit and controlling the tuning frequency through the provision of varactor diodes at the primary and the secondary side of this circuit. CONSTITUTION:The phase shift circuit 4 consists of the dual tuning circuit consisting of transformers 4a, 4c and capacitors 4b, 4d and varactor diodes 12, 14 are respectively placed to the primary and the secondary sides. The tuning frequency is controlled by controlling the capacitance value of the diodes 12, 14 with the DC signal obtained through the DC amplifier 17 from the output of the multiplication circuit 3. Since the circuit 4 uses dual tuning circuit, the extent of phase shift for the signal at the tuning frequency is comparatively greater, 90 deg., enabling to increase the S/N of the FM detection signal. Further, the tuning frequency is followed to the intermediate frequency by controlling the diodes 12, 14 to minimize the extent of distortion of detection and the DC level variation of the detection signal can be suppressed.
